SURGICAL DEVICE.

Application filed May 1,

To all whom it may concern:

Be it known that I, ALFRED H. BRAEOK- LEIN, a citizen of the UnitedStates, residing at Baltimore, in the county of Baltimore City and Stateof Maryland, have invented new and useful Improvements in SurgicalDevices, of which the following 15 a specification.

This invention relates to improvement in tourniquets.

An object of the present invention is to provide a tourniquet which isespecially adapted for use in intravenous treatments in that it may beeasily and instantly released without interference with the operationor'danger of the needle being accidentall withdrawn from the vein.

Anot er object of the invention is the provision of a tourniquet wherebyan even pull may be made in adjusting the loop, so that an even pressureall around is exerted and folding or pinching of the flesh prevented,provision being made for taking care of such flesh as might be gathered,without inconvenience to the patient.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyindrawings and pointed out in the appends claims.

In the drawings Figure 1 is a plan view of the invention.

Figure 2 is a central longitudinal sectional view of the same.

Figure 3 is a detail perspective view of the clamping member.

Referring in detail to the drawings wherein like characters of referencedenote corresponding parts, the reference character 10 indicates aflexible. member which may be formed of rubber or other suitablematerial. This member is arranged to provide a loop 11 and for thispurpose there is utilized a clamp 12 through which the ends of the loop11 pass.

The clamp 12 is of tubular construction being preferably rectangular incross sec.- tion, being of suflicient transverse area to permit of thefree passage of the ends of the loop. The side walls of one end of thetubular member are outwardly flared as indicated at 13 and this end ofthe said member is also provided with oppositely extending rightangularly disposed flanges 14 1923. Serial No. 638,012.

which provide transversely aligned faces 15. The construction at thisend of the tubular member permits of the formation of a substantiallyround loop without abruptly bending the flexible member 10, the faces 15forming a portion of this loop as will be readily seen by reference tothe dotted loop shown in Figure 1 of the drawings. Also, by thisarrangement any tendency of the patients flesh to gather will be takencare of at this portion of the loop. It is to be observed however thatthis tendency is ractically entirely eliminated by reason 0 the factthat both ends of the loop may be simultaneously drawn through thetubular pressure is provided all around.

The side walls of the tubular member are provided with oppositelylocated inclined.

slots 16 and extending through these slots is a bar 17 which, as shownin Figure 2, is adapted to bite into and clam the flexible member 10 soas to resist en argement of the loop but will permit free relativemovement of the flexible member and clam for the purpose of reducing thesize of the cop.

To provide suflicient length for the slots 16, the tubular member isformed with an oflset 18 while the bar 17 at each end is provided with aknob or head 19. These knobs or heads act to hold the bar in place andprovide means whereby the bar may be readily moved to released positionand pen mit of free movement of the flexible memher in either direction.

It will be apparent from the foregoing description and accompanyingdrawings that the invention provides a tourniquet which may be used forany and all urposes for which such a device is adapte It is especiallyadapted however for intravenous treatments in that it is capable ofbeing easily and instantly'released.

The invention is susceptible of various changes in its form, proportionsand minor 100 details of construction and the right is herein reservedto make such changes as propeply fall within the scope of the appended caims.

Having described the invention what is 105 prising a tubular memberadapted to receive both ends of the loop a tiered mouth at one end ofsaid t ubular' membei' for the passage of the flexible member, spacedflanges extending upon opposite sides of the mouth, means carried by thetubular member and engaging the flexible member to permit movement ofthe latter through the tubular member in one direction, but holding theflexible member against movement in an opposite direction and meanswhereby the holding means may be instantly released;
